DpnI requires the presence of N6-methyladenine within the recognition sequence to cleave DNA. DNA purified from a dam+ strain will be a substrate for DpnI. DpnI will only cleave fully-adenomethylated dam sites. Hemi-adenomethylated dam sites DpnI cleaves 60X more slowly. DpnI, Bsp143I, and MboI all recognize the same sequence, but have different methylation sensitivities and cleavage sites. Assayed using pBR322 DNA.
